4.4 Routing the CAN bus backbone
CAUTION!
Maximum backbone length
Possible consequence: Malfunctions.
–
The maximum backbone length (without branching
cables) must be less than 400 m
CAUTION!
Maximum length of branching cables
The T-pieces and connecting cables (branching
cables) enclosed with the modules (M-, A-, G-, N-, R-,
I- modules, CAN sensors and metering pumps with
CAN bus must be used.
Branching cables are the connections branching from
the CAN bus backbone to the modules.
The external modules can be placed in any sequence
along the CAN bus backbone. The operating instruc‐
tions show for example possible sequences of the
external modules.
Each CAN cable has a plug or coupling on each end
so that these can be coupled together in sequence to
create longer cables.
Rule
Arrange the external modules in groups for each pool.
First assemble and install the external modules and
their attachments. Only then should you connect the
external modules with the CAN bus backbone and with
each other via the the shortest route.

ficient to use the sample water limit contact of the inline probe housing on its own in order to stop the con‐
trol for the corresponding pool (contact K1 of the M
module).
The pool controller must also be set to Pause using
the contact K2 ‘Pause control ’ of the M module.
Suitable triggers are:
–
–
–
the zero volt contact of the filter control
the zero volt contact of the circulation pump's
motor protection switch
a flow monitor in the circulation line
WARNING!
Safe operating status
Both hardware and software safety precautions must
be taken to ensure that the DULCOMARIN® II adopts a
safe operating status in the event of a fault. E.g. use
limit switches, mechanical locks, ...
During installation the device must not be electrically
live.
The installation must only be carried out by technically
trained personnel.

Functional description

Functional description
The DXCa is a measuring and control unit designed to handle the
specific requirements of drinking water treatment.
For this reason it is extremely versatile when combined with a var‐
ious different measuring and actuating modules.
ProMinent uses a bus system in the DXCa in order to network the
sensors and actuators with the controller.
The standard bus system CANopen® is used.
All of the modules work according to Plug & Play principles. This is
a flexible system that can be realised to meet the requirements of a
compact or decentralised modular system and which is ready for
any future requirements that may be needed.
The DXCa can process measured values from up to 16 systems /
pools.
The I-Module enables up to 3 (third-party)-sensors with mA signals
to be connected per system / pool, e.g. for flow, turbidity and UV
intensity.
Metering pumps, chlorine gas metering systems or chlorine dioxide
production plants can be controlled directly in relation to these
measured parameters. There is also the option of using the flow
signal as interference value for the controlled measured variables.
The DXCa is equipped with an integrated data logger and option‐
ally an embedded web server and OPC server, which enables the
measured values and messages to be transferred to a control
panel via LAN/Ethernet.

Emergency measures
The plant operator is responsible for establishing a set
of emergency measures for the event of a chloric gas
leak.
All persons who are able to do so are responsible for
carrying out such emergency measures in the event of
a chloric gas leak.
WARNING!
Chloric gas can leak
Shut off the chloric gas metering system before com‐
missioning. Otherwise chloric gas can leak out.
Check and enable an emergency stop system for the
chloric gas metering system and emergency measures
before commissioning.

Fig. 10: The permanent display for all measured variables
The permanent display shows you all available measured values
from the sampled water on a system. In the event that a limit value
is exceeded (red) or undershot (blue), then a red or blue chevron is
shown next to the measured value and the measured value is
shown in the same colour.
In the event that a sensor-related fault occurs or the calibration is
faulty, then an error message appears in the corresponding meas‐
ured variable field. In the field at the bottom right-hand side, the
permanent display shows the system number, the date and time
and whether or not the metering system has been switched on or
off by means of the START/STOP key. ‘ON’ or ‘OFF’ .
By pressing F4 (GLOBAL), you can obtain an overview of all meas‐
ured values and the set points for all systems / pools, if numerous
systems / pools have been configured.

The DXCa calculates the displayed value for
bonded chlorine as the difference between the
measured values from the free chlorine and total
chlorine sensors.
Each measured variable is assigned a fixed colour
(e.g. pH = orange, redox = yellow, etc. )
You can toggle from any menu item back to the
operating menu by pressing the ESC key until the
preeminent display is shown.

Fig. 11: The central menu item for all measured variables
The central menu item shows you the same data as the permanent
display. However, it can additionally show the set points, the
switching point for bonded chlorine or the temperature.
If a measured variable is controlled, then the coloured bars cover
the entire width of the display. If a measured variable is only being
displayed, then the coloured bars only cover half the width of the
display.
In the event that there is insufficient space on the display for all of
the measured variables, then you must subdivide them. This can
be achieved by classifying a set of measured variables and
assigning them to a second, virtual pool. These two pools will be
defined as subsystems and you can name them in the same way,
but, for example, with extensions to the names ‘_A’ and ‘_B’ in
order to tell them apart.
In contrast to the permanent display, the central menu point for the
individual measured variables on a system indicates whether the
metering system is set to ‘OFF’ or ‘ ON’ . Then it shows you the
value of the actuating variable. If you have set the metering system
to ‘OFF’ then it cannot be switched on by means of the START/
STOP key.
Underneath the field with the measured variables, the central menu
item shows you the fault messages. In the event that more than
one fault message is pending, then after acknowledging the alarm
via F5, the function ‘LIST is shown’ : When you press the F5 key, a
list of the errors appears. Here you have the option of toggling over
to an archive of previous fault messages with the F5 key
(ARCHIVE) if an SD card is available for storage. You can return to
the previous display by pressing the ESC key.
For each event, the following can be detailed:
n 1. Block: Number, date, time, COMES / GOES*
– * Designates whether the error occurred or disappeared at
this point in time
n 2. Block: Node-ID, system number
n 3. Block: Error message
On the SD card, this data is stored in file ‘eventlog.txt’ . This can be
read on a PC using a word processing application.
The central menu item braches off into the settings menus

– If you calibrated with pH correction, then you may
only measure with pH correction! If you calibrated

– Following the replacement of a sensor membrane
cap or electrolyte, the slope has to be calibrated
– The slope has to be calibrated at regular intervals
to ensure the optimal operation of the sensor. Cali‐
brating the sensor every 3-4 weeks suffices with
swimming pool or potable water
– Avoid air bubbles in the measured water. Air bub‐
bles, which adhere to the membrane of the sensor,
can result in too low a reading and thus lead to
over-metering.

Repeat the calibration after one day.
You can display the pH value, the sensor current and
the temperature at the time of pressing the button with
F4 (MESS).

In the event that an error message is shown when
calibrating a chlorine sensor, you can call up
detailed information with F3 INFO. This data will
also help when discussing the matter with a tech‐
nical consultant.
In the event that the DXCa indicates an excessively low measured
value or cannot be calibrated after the sensor has been run in (for
CLE 3.1 and CTE/CGE approx. 2-6 h, for CLE 3 approx. 2 h) (in
the sample water there must be approx. 1 mg/l of free chlorine, the
pH-value 7.2 and the sample water and circulation pumps must be
running), then the run-in times should be doubled and extended
into the following day.
If the sensor still cannot not be calibrated, then please phone
ProMinent customer service. Please have the following data ready:
n DPD1-value (free chlorine)
n DPD 1 + 3-value (total chlorine)
n Primary sensor current in pA (via F4 MESS in calibration menu
for slope)
n pH value
n Redox value (if redox measurement is available)

8.6 Calibrate measured variable for chlorine dioxide (CIO2).
Calibrating at a higher temperature
As chlorine dioxide in the sample water is only physi‐
cally dissolved, unlike chlorine, it gasses out of the
sample water very quickly at high temperatures (> 30
°C). It is therefore essential that the DPD measure‐
ments are performed quickly. There should on no
account be more than 1 minute between taking the
sample and mixing it with the reagents. In this case
you must generate the red dye by the addition of the
reagent directly at the sampling point and then the
measurement should be conducted in the laboratory
as quickly as possible.
In the event that the DXCa indicates an excessively
low measured value or cannot be calibrated after the
sensor has been run in (for CDE approx. 2 - 6 hrs)
then the run-in times should be doubled and extended
into the following day.
If the sensor still cannot not be calibrated, then please
phone ProMinent customer service.

synchronously with a reduction in the circulating output. Eco!Mode
is activated or deactivated as soon as a contact is switched on

This setting under Parameter > Redox > Alarm enables the
‘Chlorine’ metering to be influenced by the ‘Redox’ measured var‐
iable.
Example: ‘Chlorine dosing redox dependent’ is active and set
value Chlorine is 100%
k=0.5 and redox ➨ "Cl Limit" = 800 mV
n Reading ‘Redox’ is < than redox ➨ ‘Cl Limit’ = 800 mV
– then the ‘Cl’ set value remains unchanged at 100%
n Reading ‘Redox’ is > than redox ➨ ‘Cl Limit’ = 800 mV
– then the ‘Cl’ set value is multiplied by ‘k’
– ➨ 100 % * 0,50 ➨ 50 % reduction in ‘Cl’ metering
If k=1 then Xp = 100 mV value for proportional metering
n Reading ‘Redox’ is < than redox ➨ ‘Cl Limit’ = 800 mV
– then the ‘Cl’ set value remains unchanged at 100%
n Reading ‘Redox’ (801 mV) is > than redox ➨ ‘Cl Limit’ = 800
mV
– then the ‘Cl’ Set value 100 % - (801-800) * 100 % / 100 =
99 %

– then the ‘Cl’ Set value 100 % - (910-800) * 100 % / 100 = 0

This behaviour enables a reduction in chlorine
metering, despite the fact that according to the chlorine
measurement, the proportion of ‘Chlorine’ in the
sample water is too low. However, due to the high
redox potential, a sufficient level of disinfection is still
ensured.

to pause via the M module contact K2. ‘K2 ACTIVE’
n M module contact K3 (this must be set to ‘Excess chlorination’
or ‘Excess chlorination & Eco!Mode’ ) serves to force the
chlorine actuator ‘active’ if K2 and K3 are both ‘active’ .
n Controllable with a configurable percentage input (0-100%) and
duration limited from 1 - 20 minutes
n This only applies to the chlorine actuating variable - all others
are set to pause.
n The control is realised without controller and without considera‐

The switching times of the DXCa (solenoid valve) depend on the
actuating variable and the ‘min. time’ (smallest permissible switchon time for the connected device). The actuating variable deter‐
mines the ratio ton/cycle and thus also the switching times (see
Fig. 97). The ‘min. time’ affects the switching times in two situa‐
tions:

CAN pumps must also be assigned to the pool even for systems
with only a single pool. The metering output curves are stored for
each stroke length at a constant back pressure of 1.5 bar in each
Beta/4-CANopen. In the event that the stroke length varies by
more than ±10 %, the DXCa signals an alarm and a message is
shown on the display. However, the pump continues to operate.
After the settings are stored (calibration), the message disappears
and the DXCa will match the pump output to the new metering
output curve.
Chlorine standby pump
The DXCa can control up to 4 metering pumps with CAN bus con‐
nection. It is possible to configure a metering pump for chlorine
next to the main chlorine pump as a standby pump.
In this case, the screen writer must be activated and an SD card
must be inserted, as this stores the operating states in an event file
on the SD card (see supplementary instructions screen writer).
The following situations cause switchover to the standby pump:
n Fault in the main chlorine pump
n Chlorine chemical reservoir on the main pump is empty
n The multifunctional switch on the main pump is set to ‘Stop’ .
However, a power failure or disconnection of the bus connection to
the main pump will not cause switchover to the standby pump.
Pump NH4OH
In the event that CAN-pumps are configured for chlorine regulation,
then a pump can also be configured via "Pump NH4OH" for pur‐
poses of chloramination. In order to do so, an ammonia solution is
metered in parallel to the chlorine solution. In order to achieve the
correct stoichiometry, the concentration of the ammonia solution
and the stroke length of the ammonia pump must be matched to
the chlorine concentration in the treated water.

Actuating variable
An actuating variable is considered to be the value (e.g. fre‐
quency, mA signal) that the controller emits to the actuator
e.g. a metering pump in order to achieve the set point again
(at actuating variable 100% a pump will run at full power).
Additive interference variable
The additive interference variable switch is suitable for
metering tasks, in which the metering volume is dependent
in the first place on the interference variable (e.g. flow) and
requires only minimal recorrection. This nature of interfer‐
ence variable processing is used, for example, in the chlori‐
nation of water with approximately constant chlorine uptake.
An interference value-related base load metering value will
be added or subtracted from the first "determined actuating
variable" from the controller. The actuating variable can be a
maximum of 100 %.
Actuating variable to actuator [%] = (recorded actuating vari‐
able [%] +max. additive actuating variable [%]*current inter‐
ference variable [mA]) / nominal interference variable [mA]
Legends: The maximum additive interference variable indi‐
cates which maximum interference variable is to be added
(where current interference variable = nominal interference
variable). For further legends see ‘multiplicative interference
value’ .
CAUTION: If there is no current interference variable (flow =
0), but a recorded actuating variable of the PID control, then
the final actuating variable corresponds to the recorded
actuating variable of the PID control. If a current interference
variable (flow = 0) is given and the detected interference
value of the PID controller is the same ‘0’ , then the final
actuating variable will correspond to the 2nd term from the
above formula:
(max. additive actuating variable * current interference variable)
/ nominal interference variable
Calibration
Transducers require calibration (alignment of the zero point
and slope).
For 1-point calibration, this is undertaken with a buffer solu‐
tion pH 7. I.e. only the zero point is calibrated in this case.
184
For 2-point calibration it is necessary to select a second
value in order to calibrate the slope: e.g. pH 4 or pH 10. The
second value is dependent on the actual measurement
range (alkali or acid).
In swimming pool technology it is sufficient to carry out a
zero point calibration (at pH 7) and merely to check the
sensor function with a buffer solution at pH 4 or pH 10. As
the measurement is undertaken around the zero point, mod‐
erate errors in the slope are immaterial
The slope of the sensor can change as a result of aging and
soiling.
checkout time
CAUTION: The function ‘checkout time control’ can be con‐
fused with ‘Control time of reading’ on the DULCOMETER®
D1C!
The function ‘checkout time control’ offers a protection
option against the risk of over-metering. It switches the
respective control circuit to metering 0% after expiration of
the checkout time and triggers an error message if:
On a pure P control: the P proportion of the actuating vari‐
able is greater than 40%.
for PID control: the PID actuating variable Y is greater than
90%.
Press the start / stop button twice in order to restart the
respective control circuit and to delete the error message for
the control circuit.
Control equations:
Normal
A measured value is compared with a set point. In the event
of a control difference (difference of set point minus actual
value), an actuating value is determined which will counter
the control difference.
Controller
The DXCa controller be used as a P-, PI-, or PID-controller.
This depends on the settings of the control parameters.
The actuating variable is calculated once per second.
This controller cannot be used in control circuits that require
quicker reactions to control deviations (less than 30 sec‐
onds).
The control function (output of actuating variables) can be
switched off by means of the Pause control input.
Actuating variable calculation is resumed as soon as Pause
is ceased.
Control variable (measured value,
actual value)
The control variable is the variable which is to be measured
and recorded (e.g. pH value, redox value).
Delay (alarm limits)
In the event that the alarm threshold is violated, the DXCa
will trigger an error message only after the configured delay
set here. This means that brief alarm threshold violations will
not trigger an error message.
Delay (contact)
As soon as a contact is connected to a contact input K of the
M module, the DXCa sets the actuating outputs to ‘0’ for as
long as the contact is made and for a subsequent delay
period (contact) (if it has been configured). While the contact
is made, the DXCa suppresses error treatment. As soon as
the contact is opened, the DXCa commences with error
treatment again - after the delay period has expired (contact)
(if it has been configured). Once the contact has been
opened, the actuating outputs remain - for the duration of the
delay (contact) - at ‘0’ . The delay (contact) has to be set in
185
such a way that, for example, during this time sample water
with the current concentration relative to the process flows to
the sensor. The delay (contact) from "pause control" has a
higher priority that the delay (contact) from ‘ Sampling
water’ . The 0/4-20 mA outputs (standard signal outputs) for
the reading or correction value are unaffected by this func‐
tion.
Delay (error)
In the event of a limit value violation, the limit value relay of
the G module will trip after the delay period entered here has
elapsed. This means that brief limit value violations will not
trigger an error message.
Determining the checkout time
Prerequisites:
The system has achieved the set points for chlorine concen‐
tration (0.45 mg/l) and pH value.
Stop the system using the Start/Stop key.
Wait until the chlorine concentration has dropped to 0.1 mg/l.
Restart the controller using the Start/Stop key.
Measure the time needed until the set point has been ach‐
ieved.
Enter this time multiplied by 1.5 as the checkout time for
chlorine concentration.
If the pump capacities are correctly selected, then this
checkout time can also be entered for the pH value.
Eco!Mode
‘Eco!Mode’ enables a 2nd set of parameters to be tempora‐
rily activated in order to save power. This can, for example,
be carried out synchronously with a reduction in the circu‐
lating output. As soon as a contact is switched on contact
input K3 of the M module, ‘Eco!Mode’ is activated or deacti‐
vated. Eco!Mode is available for all M module measured var‐
iables, if they are controlled:
pH
Redox
chlorine free
chlorine bound
Temperature
Flocculent
As soon as the 2nd set of parameters is activated, the cen‐
tral menu item indicates a green ECO identifier.
Interference value
The controller can process a signal from a flow measure‐
ment on the analogue input ‘I in 1’ of the DXMaI module as
an interference value for the controlled measured variables
of the I module. This interference value influences the
actuating variables calculated by the controller in relation to
the external signal.
Depending on the nature of the effect on the actuating vari‐
able, it is referred to either as a
multiplicative interference variable (flow-proportional effect)
or an
additive interference variable (interference variable-related
effect)
When ‘Commissioning’ the zero point signal of the flow
gauge has to be checked without flow (must be ≥ 0).
186
Limit values
‘min. limit’ means that the limit criterion has been trans‐
gressed by dropping below the lower limit
‘max. limit’ means that the limit criterion has been trans‐
gressed by exceeding the upper limit
Multiplicative interference variable
This type of interference variable processing is used, for
example, with flow neutralisation. The actuating variables
determined by the controller are multiplied by a factor F. The
factor lies in the range of 0 ≤ F ≤ 1 (0 ~= 0 %, 1 ~= 100 %).
The actuating variable can therefore be a maximum of 100
%.
Actuating variable to
actuator [%] = recorded actuating variable [%] * current inter‐
ference variable [mA] / nominal interference variable [mA]
A ‘current interference variable’ greater than or equal to the
‘Interference variable nominal value’ does not affect the
control variable.
Legends: The determined actuating variable is the actuating
variable which is issued by the controller without an interfer‐
ence value. The nominal interference variable limits the
range that can be used.
Example: A flow meter is used, for example, which can
measure a maximum flow of Q = 250 m3/h. The analogue
output of the flow meter supplies a signal corresponding to 4
mA = 0 m3/h, 20 mA = 250 m3/h. The maximum flow that
can be achieved in the application is however only 125 m3/h.
If the standard signal-output signal of the flow meter is now
not adjusted to the 4...20 mA range of the D1C (possible
with the majority of flow meters), then the standard signal at
125 m3/h is only12 mA. Is this value then to be entered into
the ‘interference value menu?’ Enter under ‘Interference
variable nominal value’ .
The interference variable is the current analogue flow, which
the flow meter supplies. The final actuating variable is trans‐
ferred to the actuator.
The multiplicative interference value is not designed to per‐
manently switch off the actuating variable! In this case you
should realise deactivation via the pause function.
Pause
When the Pause contact is closed, the DXCa sets all
actuating outputs to ‘0’ for as long as the pause contact is
closed. While the Pause contact is closed, the DXC records
the P-proportion in the background.
pH value
pH-value refers to a measurement for the concentration
(activity) of hydrogen ions or, put simply, is a measurement
for the acidity or alkalinity of water.
The pH value is of great importance in terms of swimming
pool water treatment. It influences:
the degree of disinfection: the disinfection effect of chlorine
reduces as the pH value rises
the flocculent: every flocculent has only a certain pH range
in which it is able to work optimally
the corrosiveness: the corrosiveness of the water increases
as the pH value drops. Mechanical materials will corrode
The skin tolerance: The acidic protection layer of our skin is
pH 5.5. Excessive pH values in the swimming pool water
attack the protective layers of skin and this leads to skin irri‐
tation.
187
An excessively low pH value increases the likelihood of trichloramine formation. This can lead to eye irritation
(inflamed, stringing eyes) and mucous membrane irritation
(e.g. coughing). For these reasons, the pH value of swim‐
ming pool water should always be in the range between 6.5
and 7.6 (optimal: pH-optimum of the flocculent used). In pri‐
vate swimming pools, where generally no flocculants are
uses, the pH value should lie between 7 and 7.2.
On the other hand, the pH measurement is influenced by the
following factors:
chlorination: all chlorine products will change the pH value
the water distribution: carbon dioxide (CO2) outgassing from
the pool water will raise the pH value. This effect can be
amplified by an unfavourable water distribution or by aera‐
tors, fungi or similar.
For these reasons, the pH value must be constantly meas‐
ured and controlled.
Redox voltage
The redox voltage is dependent on the sum total of reductive
and oxidising substances contained in the water. It repre‐
sents a measurement for the disinfecting efficiency of the
water. The higher the concentration of oxidising substances,
the greater the redox voltage (oxidation = disinfection).
In a swimming pool, hypochlorous acid is the determining
oxidising substance. Contaminating substances are mini‐
mised.
pH-value and temperature have the following influences on
the redox value:
Increasing pH-value--> decreasing redox voltage
Increasing temperature--> increasing redox voltage
A stable pH value is extremely important!
There is no unequivocal relationship between disinfectant
concentration and redox voltage. At a redox voltage of 750
mV it is assured that introduced microorganisms are
destroyed or made inactive in a matter of seconds. At values
lower than 600 mV the disinfection period can amount to
minutes or hours.
Set point
Set point refers to a value which is to be maintained at a
constant level by means of the controllers in a process.
Slope / sensitivity
This value is, for example, given in mV/pH at 25 °C.
Types of controller:
P controller:
Is used in controlled systems which work in an integrated
manner (e.g. batch neutralisation).
PI controller:
Can be used in non-integrated controlled systems (e.g. flow
neutralisation).
PID controller:
Is used in controlled systems where peaks occur that have
to be compensated for.
With dead zone:
With dead zone control (neutral zone control) two set points
have to be specified. If the reading is located within the dead
zone, then no control variable will be issued.
Set point 2 must be greater than set point 1!
188
Manual
ATTENTION: The controller will not exit this mode automati‐
cally. Manual mode may only be used for commissioning
and for test purposes.
There is no control. An actuating variable will be specified
manually:
Actuating variable: 0...+100 % (actuating output rise active)
Actuating variable: -100...0 % (actuating output lower active)
This function is used to monitor actuators.
Additive basic load:
A basic load is added to the current actuating variable. The
additive basic load means that, for example, constant attri‐
tion can be compensated for.
YTot = Yp + 15 % (additive basic load = 15 %)
Example 1 (one-way control): YTot = 85 % + 15 %; YTot = 100
%
Example 2 (one-way control): YTot = -75 % + 15 %; YTot = -60
%
xp value
This value influences the proportional control behaviour. For
example, an xp of 1.4 pH with a deviation of +1.4 pH leads
to an actuating variable of -100% or at a deviation of -1.4 pH
to an actuating variable of +100%. In other words, if a devia‐
tion occurs to the size of xp, then an actuating variable of
100% follows.
Zero point
This refers to, for example, the voltage that a pH sensor
emits at pH value 7. The zero point of the sensor can
change as a result of aging and soiling.
The zero point of pH sensors is theoretically 0 mV. In prac‐
tical terms, a zero point between -30 mV and +30 mV is
acceptable for good sensor operation. New sensors have a
zero point tolerance of max. ±30 mV.

About this product
The screen plotter for the swimming pool controller DULCO‐
MARIN® II is a software solution, which makes an expensive addi‐
tional device superfluous. It is designed as a 16-times 2 x 5
channel plotter. It displays the measured values for pH value,
redox value, free Cl and combined Cl and the temperature, as well
as the corresponding control variables (not for temperature), and
this for up to 16 pools. Without an SD-card it can save measure‐
ment results for 24 h, with an SD-card it can save measurement
results from 35 days up to 12 years, dependent on requirements.
Single TXT files from the SD card can be copied to a PC and, for
example, processed with EXCEL to create graphics.

Measured variable chart
The measured variable chart shows the y-axis and units on the
extreme left. The time axis (x-axis) is located between the meas‐
ured variable chart and the control variable chart. It always shows
24 hours. It only shows hour times where there are measured
values. Otherwise it shows ‘00:00’ .
The red lines indicate the set limit values (in the parameter menu:
Parameter Alarm). If the measured values exceed the limit values,
the measurement curve appears red in this position.
The blue line is a cursor, with which individual measured values
can be approached, so that their precise value can be read off (see
under ‘Info line for the selected measured value’ and ‘Bar with
function keys’ ). Initially it is positioned exactly on the y-axis.
Chart for the control variable of the
measured variable
The chart for the control variable of the measured variable shows
the y-axis on the extreme left with ‘%’ units. The time axis (x-axis)
is located between the chart for the measured variable and the
chart for the control variable. It always shows 24 hours.
201
Information line for the selected
measured value
The information line for the selected measured value shows its pre‐
cise value. You select a measured value using the cursor (see

Normal view
If the plotter takes the next measured value, the view
jumps back to the normal view (after no more than 5
minutes). Each change to another display resets the
view to the normal view.
Using the function key [ARCHIVE] you can check historical meas‐
ured values on the DULCOMARIN® II (values going back up to a
week). For this, you require an SD card. The function key bar con‐
tains the [ARCHIVE] function key as well as the function key pairs
[F2 ZOOM- ]/ [F3 ZOOM+] and[ F4 <CURSOR ]/ F5 CURSOR>:
The function key pair [F2 ZOOM-] / [F3 ZOOM+] is used to zoom
the y-axis for the measured variable.
The function key pair [F4 <CURSOR] / [F5 CURSOR>] is used to
move the blue cursor in the measured variable chart (it may pos‐
sibly initially be located on the y-axis).
More information
The time interval over which the DULCOMARIN® II plots the meas‐
ured values is 5 minutes. If the measurement curve has reached
the chart width, then for each new value on the right, an old value
disappears on the left.
The DULCOMARIN® II saves the measured values for the current
day. The DULCOMARIN® II saves the measured values of the last
day from 00:00 to 24:00 h as a file for each measured variable and
for each pool.
If an SD card is inserted, then the DULCOMARIN® II saves these
files on the SD card until it is full.
Using the function key [ARCHIVE] you can check historical meas‐
ured values on the DULCOMARIN® II, for periods going back up to
a week. In the archive you can use the function keys [<< ]and [>>]
to jump from day to day. The display shows the numbers of the
days in the top right corner.

Using an SD card
NOTICE!
Before expiry of the number of maximum savable days
you must replace the full SD card for an empty SD
card.
Otherwise, the data for further days are lost, as the
DULCOMARIN® II cannot delete the data on the SD
card.
Requirement
A PC with at least WIN98 and a USB port.
If the measured values of the plotter are to be saved
for longer than 24 h, you must use an SD card.
The screen plotter shows the measured values for the
last 24 h. You can call up older measured values using
the [ARCHIVE] function key or load them on a PC

Using an SD card
The transparent interface cover (3) in Fig. 5 must be
screwed in place again so that it is moisture-proof.
Otherwise the IP 65 rating is not achieved.
Evaluation of the SD card files
1.
To remove the SD card open the transparent interface cover
(3) at the bottom of the DXC housing of the
DULCOMARIN® II (shown Fig. 5 opened)
2.
Only pull out the SD card (2) from the card slot (1), if the
identifier ‘SD’ , at the top right on the LCD screen is high‐
lighted in green. Not when it is highlighted in red! The plotter
is then saving data. In this case wait briefly.
ð Once you have pulled out the SD card, the identifier ‘SD’
at the top right of the LCD screen disappears. Moreover
the error message ‘! Please insert SD card !!’ appears in
the continuous display and in the central menu item.
3.
Copy the files contained in the SD card to a PC via a card
reader and then delete the the SD card contents.
4.
Push the SD card (2) into the card slot (1) until it engages
ð Then at the top right on the LCD screen, the ‘SD’ identi‐
fier appears highlighted in green. Moreover, the error
message ‘! Please insert SD card !’ disappears.
To protect the data, the DULCOMARIN® II saves the
files with ‘write protection’ . When working, only use
copies and clear the file write-protection on the PC
under ‘Properties’ .
If you have changed the clock of the DULCOMARIN® II
from or to summer time, bear this in mind during data
evaluation.

About this device
The control module DXMaA allows the DULCOMARIN® II to control
3 metering pumps by pulse frequency, e.g. to increase or lower the
pH value or to meter disinfectant.
The DXMaA control module has the following outputs:
n Four standard signal outputs 0/4...20 mA, freely programmable
and scalable for measured values, e.g. of pH value, redox
voltage, the concentration of free chlorine or total chlorine or
combined chlorine or temperature.
n Three frequency outputs for controlling metering pumps e.g. to
increase or lower the pH value or to meter disinfectant
and the following inputs:
n Three contact inputs for evaluating the fault indicating relay of
the metering pumps and monitoring the container fill level
2.1 Safety chapter
The DXMaA control module must only be used as part of the
DULCOMARIN® II.
The installation must only be carried out by technically trained per‐
sonnel.
CAUTION!

NOTICE!
trained personnel.
When assembling and installing this device, observe
the instructions in the operating instructions "Multichannel measuring and control system
DULCOMARIN® II Swimming Pool Controller and Dis‐
infection Controller DXCa Part 1: Assembly and instal‐
lation".
Incorrect measured values
The standard signals can be falsified, possibly with
consequences for the process.
You may only directly connect devices with autono‐
mous galvanic isolation of the individual standard
signal inputs to the standard signal outputs (e.g. the
standard signal inputs of a plotter,...)!
If you want to connect a multi-channel standard signal
input module of a PLC to several standard signal out‐
puts of the DXMaA module, then you must route each
standard signal wire via a 3-way standard signal iso‐
lator. A 3-way standard signal isolator galvanically iso‐
lates the input, the output and the supply voltage from
each other.
Where there are several standard signal wires, a multichannel isolating amplifier can be used. ProMinent rec‐
ommends 4-channel isolating amplifiers of type LCTV-4I.4I as supplied by Rinck www.rinck-electronic.de
or of type 6185D supplied by PR Electronics
www.prelectronics.de for the connection of up to 4
standard signal wires.
Make the CAN connection according to the "Multi-channel meas‐
uring and control system operating instructions DULCOMARIN® II
Swimming Pool Controller and Disinfection Controller DXCa Part 1,
Assembly and Installation".

G module, DXMaG description
The G module is a limit value or alarm generator module. It has
two potential-free changer relays for signalling alarm states.
Each of the two relays has different setting options, which can
influence the relay effects.
Both relays offer the same setting options.
Hence through the use of different delay periods, pre-warning or
shut-down signals can be generated.

About this device
The current input module DXMaI allows the DULCOMARIN® II to
connect 2 switches / relays and 3 sensors via 0/4...20 mA inputs.
The DXMaI control module has the following inputs:
n Contact inputs for sample water monitoring and pause
n 3 standard signal inputs 0/4...20 mA
The mA values of the sensors for flow, turbidity, UV-intensity, con‐
ductive conductivity, dissolved oxygen and ammonia are received
already processed (compensated and calibrated).
The mA values for ClO2, H2O2, PES, fluoride and chlorite can be
temperature compensated. To do this, a PT1000 sensor with mA
transformer must be connected to an mA input.

6.2 Calibration
6.2.1 pH calibration
Calibration of pH measurement
Automatic buffer detection
The condition of a pH sensor is decisive for the quality
of the measurement. Therefore each pH sensor must
periodically be recalibrated using buffer solutions. The
DXMaM has an automatic buffer detection system for
the buffer solution being used.
The following buffer table is stored in the program memory:

Large quantities of chlorine gas can escape if an
uncontrolled chlorine gas metering device is set to
‘ON’ . Chlorine gas can escape into the swimming pool
hall.
Measure: Lock the power supply to the chlorine gas
metering device to allow for a power failure occurring;
do likewise with the power supplies to the booster
pump and the circulating pump, to ensure these
pumps remain inactive.

CAUTION!
Thermal overloading of the pump motor
Consequence: The pump motor and its surroundings
could be damaged
Measure: Provide the pump motor and/or the fre‐
quency converter with a suitable thermal protection
switch and possibly a fan.
In this respect observe the peculiarities of your local
ambient conditions and your national regulations and
standards.
The operating mode [ECO Mode min. circulation capacity] speci‐
fies how far the circulation capacity of the circulating pumps is
reduced in [ECO Mode].
Operating mode [DIN Error ➨ 100%], immediately sets the circula‐
tion operating mode to [normal mode] if the active ECO limit value
settings are breached. Otherwise the circulation increases in par‐
allel with the values of the reduction mode.
Operating mode [Redox ➨ Circulation (dependency) cor.: active]:
In this operating mode, the reduction rate is influenced by the
actual redox value Start and end redox values are defined. Reduc‐
tion mode is started from the start Redox value. Reduction mode
lowers the circulating pump capacity in steps up until the End
redox value the [ECO Mode min] value is reached. If the water
redox value falls below the start redox value, then the circulation
starts again at 100% capacity.
Operating mode [Redox ➨ Circulation (dependency) cor.: inactive]:
In this operating mode, the reduction rate [Circulation reduction %]
and the time period [Circulation reduction time = seconds ] are set.
This reduction [Step reductions] is continued downwards until the
set value [ECOMode min] is reached.
The operating mode [Circulation reduction in %] in which the time
period in [sec] is set. This reduction [Step reductions] is continued
until the set [ECO Mode min] value is reached.

Flow control [water flow]
3
NOTICE!
Alarm during logical checking
Cause: Alarm during logical checking.
Fault: The flow control reports that a water flow exists,
although the circulating pump is off.
Measure: The controller triggers an alarm. The flow
control must be checked.
NOTICE!
No flow
Cause: No flow in the water circulation system.
Fault: There is for example no water in the system or a
ball valve is closed.
The controller switches the circulating pump off and
triggers an alarm.
Timer adjustments with two circulating pumps
If two circulating pumps are connected, then they must
always be started simultaneously via the time. A
delayed switching on of the pumps, resulting in
switching on at different times, is not permitted
because this leads to an error message at the control
so that consequently the second circulating pump does
not start.
Example: Both circulating pumps are stopped by the
timer. The pool has status [Stop] and consequently the
paddle switch signals are not evaluated by the con‐
troller. If the timer now starts Circulating pump 1, then
within 30 seconds paddle switch [1] must deliver feed‐
back relating to the water flow. The paddle switch [2]
delivers the signal [no water flow] (which is indeed cor‐
rect), but the control reports the error [No flow]. Hence
the circulating pump [2] cannot be automatically
started by the timer.
Remedy: Adjust the timer so that both circulating
pumps are started simultaneously. This prevents one
of the two circulating pumps from not starting.
The flow control [Water flow] monitors the circulating pump flow.
The [Flow Control] is used with a paddle switch or a thermo switch.
The [Water flow] flow control should prevent running dry of the
system or delivery from the circulating pump against a closed gate
valve. If the [water flow] flow control is activated in the A module,
then a closed [NC] contact is necessary, to make possible contin‐
uous operation of the circulation.
The two core cable of the flow checking device (paddle switch or
thermo switch) must be connected in the A-module to the [R2] ter‐
minal. If the contact remains set on [passive] during circulating
pump control, then the circulating pump is stopped after a delay
period and the control produces an error message. This error mes‐
sage can only be deleted in manual operating mode.

Timer settings
Cause: Timer setting, this means the circulation is only
active if the operator activates this circulation for
bathing/swimming operation.
The operating status of your overall system can
change at any time during the automatic operation of
the controller. In this respect for example, the circu‐
lating pump, heating etc., can start or stop at any time.
The functions and operating times, circulation and backwashing
can be set at any time using via the timer setting.
In operating mode [Actuator module] under [Options], in operating
mode [Circulation] the various timer adjustments can be made by
activating circulation.
When setting the timer, you must check that you save
the settings after each timer adjustment. If timers 1 ...
6 are set and then saved, then only timer 6 is saved.
There are 12 timer functions available for a pool circuit:
n Timer 1 ... 6 when using Circulation 1
n Timer 7 ... 12 when using Circulation 2

Water top-up
An automatic water top-up can be carried out in the skimmer or
surge water tank using a level contact.
Please note that the drinking water connection may not be con‐
nected to the pool circuit. See the corresponding DVGW (German
Gas and Water Association) or FIGAWA (German Federal Associ‐
ation of Gas and Water Companies) regulations or your own
national regulations.
1.
Connect the single-stage level switch in the A module to ter‐
minal [K1 7/8]
2.
In configuration on the A module set terminal [R1] to ‘free’
3.
Thereafter terminal [K1] can be activated as a water level
4.
If the [TIME] [water level] is set to [0 s], then after
10 seconds constantly at the minimum level, the
Level evaluation unit reacts by opening the water
supply solenoid valve. After 10 seconds con‐
stantly at the maximum liquid level, the solenoid
valve for the water supply is closed. If a [TIME]
[water level] of for example [30 s] is set, then for
this 30 seconds water continues to be supplied,
so that the maximum liquid level is reached after
this time.
The [TIME] [water level] can be set from 0 ... 480 seconds in
steps
5.
To actuate a solenoid valve with 230 V, it is necessary to
connect this solenoid valve to the PCB of the P module on
terminal 2 (with one circulation) or terminal 1 (with two circu‐
lations)
6.
Program the configuration menu of this relay using the func‐
tion [Water top-up]
ð
If water is topped up for longer than 180
minutes the controller enters fault mode and
stops the topping up.
This this function is active
7.
If the control time has elapsed and the controller is in fault
mode, then you must press the [F3] key for [Reset] in the A
module configuration menu under service [F2]. This restarts
water top-up in operating mode [AUTO]

Control of the backwashing valves
6
Control of the backwashing valves
NOTICE!
The default state of the backwashing valves is deener‐
gised (voltage free)
Fault: No backwashing is possible if the backwashing
valves cannot be controlled.
Consequence: The hygiene parameters worsen and
the hydraulic resistance of the filter increases.
Measure: Regularly check (dependent on the applica‐
tion) the operation of filter backwash.
An automatic 6-way valve cannot be used.
For backwashing there is, for example, the option of controlling a
Besgo® rod valve.
To do this, the rod valve must be connected to terminal P3 in the P
module. If two circuits are in operation, the second rod valve must
be connected to terminal P2.
To activate this function, the function [Backwash 1] or
[Backwash 2] must be activated in the P module.
Setting of the backwashing times is described under Timer set‐
tingÄ Chapter 4 ‘Timer settings’ on page 317.
